Lots of organizations are excited about what AI can do to streamline their processes, save money, and juice margins. But AI's capabilities are founded on the data that AI accesses, and for many organizations that foundation is little more than sand. Pramod Sadalage and Prem Chandrasekaran write about how to build a reliable foundation of data that can be accurate and trusted. more… Lots of organizations are excited about what AI can do to streamline ...

Search tablesproworld com and you reach a multi-topic blog, not a single-subject site. Posts run across business, technology, health, home improvement, travel and lifestyle. The spread raises a fair question: how much of it should you act on? This guide covers what the site publishes, how the pages are arranged, and the checks worth running before you trust any article on it. What is tablesproworld com? tablesproworld com works as a general informational website. Rather than one niche, ...

At the heart of quantum mechanics lie a few sacred rules for how to use the theory. First and foremost is, roughly, that thou shalt not think about ordinary objects presently whizzing through ordinary space. Rather, quantum mechanics predicts — in exquisite detail — all the possible ways that an object might turn out to be in the future. Exploring those possible futures requires tracking an… Source At the heart of quantum mechanics lie a few sacred rules for how to use the theory. First...

A lot of people have the wrong idea about fundraising. They make fundraising a really complex thing, making it seem that you have to change your entire personality, or lie, or somehow try to fool people. After Solo Founders and Y Combinator , I’ve realized that most of that is overcomplicating things. There’s really only one thing you have to learn so you can fundraise successfully: learn to think like a VC When you have a good mental model of how a VC makes decisions wi...

For a mobile 'mini homelab' project I'm working on, I wanted to use 5G Internet as a primary 'on-to-go' connection, but still have the ability to plug in another Internet connection when I put the mobile rack I'm building in a fixed location. I'll have more on that project soon, but I figured this project was a good way to check out Ubiquiti's solutions, especially considering many of their smaller gear fits nicely within the dimensions of a mini rack (the 3U DeskPi RackMate TT is pictu...

In July, several Confluent colleagues and I published The LogDrive: Composable Durability for Cloud-Based Shared Logs . The paper evolves the concepts of Virtual Consensus in Delos by decomposing the Loglet abstraction into AtomicLog and LogDrive, moving composition below sequencing to a new durability abstraction. This post describes these new abstractions in the context of Virtual Consensus, focusing on how they support RAID-like composability for shared logs. The ideas of the paper came o...

In Java, you find the location of a substring using indexOf . String haystack = "The quick brown fox jumps over the lazy dog" ; String needle = "fox" ; int index = haystack . indexOf ( needle ); Naively, you might implement indexOf by a loop inside a loop, like so. int naiveIndexOf ( String haystack , String needle ) { for ( int i = 0 ; i m String haystack = "a" . repeat ( n ); String needle = "a" . repeat ( m ...

The US Strategic Petroleum Reserve (SPR) is the largest crude oil storage facility in the world. It’s capable of storing 714 million barrels of oil, slightly less than 10% of the US’s annual oil consumption . Built in response to OAPEC ’s 1973 oil embargo, the SPR was created to insulate the US from oil supply shocks: to make up for shortfalls and prevent steep price increases should oil imports be interrupted. In the years since its creation, it has become one of the most frequently use...

In the hours following the release of CVE-2026-41992 for the project GNU gzip , site reliability workers and systems administrators scrambled to desperately rebuild and patch all their systems to fix decompressing two files in the same invocation of gzip (that's possible???) an attacker can trigger out of bound reads in the LZH decoder, causing reads past the end of the shared global buffer that is somehow not reset between invocations. This is due to the affected components being ...

Linux 7.2 has been released! That was fast. Let’s dive in to yet another Asahi Linux progress report. We’ve got a lot of interesting developments for you today, so make yourself a cuppa and enjoy. Think Different… again The Apple Silicon platform’s power management infrastructure is complicated. Responsibilities are divided between multiple hardware blocks, including the SMC, PMGR, and PMP, all of which have featured before on this blog. While supporting these blocks is important for pow...

In the past, I have used the shorthand “if you have a website, you’re in the indie web community.” I have used this because I don’t think there are, or should be, any other qualifying factors (i.e. using particular tools, having a certain site layout). While I think this shorthand is useful in ensuring people don’t feel like they have to do things a certain way to participate in the indie web, it misses one constituency that I don’t think are talked about enough: readers. Before some...

Any rigorous thinking about the long-term future leads to extreme outcomes. It cannot, by construction, produce normal or mundane futures. “Rigorous thinking” means you have a model: a formalism for representing the state of the world, and a transition function to advance the state. You put the world into the formalism, and turn the crank to get successive states of the world. Models can be qualitative or quantitative. Most thinking about the future is qualitative and informal: people thi...

I’ve had a Synology NAS for a very long time , and recently I started moving its contents to a new Ubiquiti UniFi UNAS Pro 8 . This seemed like it ought to be a fairly boring operation. Both devices speak SMB, I have a fast network (recently upgraded to 10 gigabit internally), and Windows has had tools for copying files reliably between machines for decades. Naturally, it turned into a whole evening of learning things I thought I already knew, which is why I started a blog lol. There was...

Can you believe it’s been ten years since Brexit? In some ways it feels more recent, in others it’s as though we’ve been hearing about it from our British and European friends for a long time. I bring it up here because I’ve recently noticed an odd shift in the discussion. Pundits and commentators are concluding that the Leave and Remain campaigns were just as irrational and confused as each other a decade ago, and that lack of a positive outcome for either side is the reason for the...

speedlify.dev , now running Speedlify2 . The year is 2020. Inspired by a lack of budget for a web performance monitoring tool, the original Speedlify project (Speedlify Classic) was shipped to continuously measure site performance. It ran Lighthouse against a predetermined list of sites and ranked their performance against each other. Over time, I started to add a few more things to Speedlify. A Web Component was added to show scores on your web site. The Eleventy Leaderboards...

I frequently see statements about differences between strongly ordered architectures (like x86 or SPARC) and weakly ordered architectures (like ARM or RISC-V), with the confident assertion that weakly ordered machines are inherently much more scalable than strongly ordered ones. The key misconception is the implicit assumption that CPUs of all stripes actually obey their memory model for every memory access. They, emphatically, do not. They promise to behave as if they did. Ther...

There's a scene in Apollo 13 where Jim Lovell, played by Tom Hanks, asks Houston control to check his calculations, which they do using a slide rule.  My father told me that when he was in college (1950s) that engineers measured their technical prowess in how many digits of accuracy they could get off a slide rule. The actual Apollo 13 incident took place in 1970. A year later Bowmar/Ali released the 901B, nicknamed the Bowmar Brain, for about $240.  The following year came the HP-35, the fi...

Sean Goedecke wrote a post arguing that you should never be angry at work — a post with which I strongly agree. Anger can be a useful signal, but being angry at work rarely improves the situation. More often, it makes life worse for the people around you, many of whom have no more power over the source of your anger than you do. I did learn that lesson, but it did not come naturally. One thing in particular that I learned is that in a company there is a shared vision, and if you don’t ...

Unlike the millions of years it takes for most mountains on Earth to form, lunar mountains crop out near-instantly, geologically speaking. Mountains on our dear Earth primarily form when two colliding plates of Terra’s crust lift up volumes of rock, slowly creating an elevated landform. Over millions of years, wind, water, and gravity erode these uplifted sections, shaping their surface as the mountains we are familiar with today. But the Moon has no plate tectonics, atmosphere, or running wat...
